Foreword
The SRX120 Snowmobile is intended to be a learning/recreational snowmobile for a
responsible child at least 6 years of age under adult supervision. This snowmobile is
intended to be ridden by the operator only; there should be no passenger. Also, this
snowmobile is intended for daylight use in restricted off-road areas, primarily on
snow. Use of this snowmobile on public streets, roads, and highways can be hazardous and is prohibited by law in most cases. As a parent or guardian, one must accept
the responsibility of training the child in the safe operation of the snowmobile. Teach
all operators the basic principles of operation, snowmobile rules and regulations, and
especially how to stop the snowmobile in case of an emergency. Impress upon the
child a sense of snowmobile courtesy and responsibility.
This snowmobile is a quality Yamaha product designed, engineered, and assembled
to give dependable service. Be sure, as the owner, to become thoroughly familiar with
its basic operation, maintenance, and storage procedures. Read this manual and the
accompanying Snowmobile Safety Handbook to ensure safe and proper use of the
snowmobile.
This manual is divided into sections. The sections Getting Ready to Operate the
SRX120 Safely and Operating the SRX120 must be read and explained to the child/
operator. The other sections are for the owner/parent/guardian and contain information on snowmobile identification, safe operating instructions, lubrication, maintenance, storage, and after-storage preparation. If repair or service is ever required,
contact an authorized Yamaha Snowmobile dealer for professional service.
The Operator’s Manual, Snowmobile Safety Handbook, and snowmobile decals display the words Warning, Caution, and Note to emphasize important information. The
symbol WARNING identifies personal safety-related information. Be sure to follow the directive because it deals with the possibility of severe personal injury or
even death. A CAUTION identifies unsafe practices which may result in snowmobile-related damage. Follow the directive because it deals with the possibility of damaging part or parts of the snowmobile. The symbol
supplementary information worthy of particular attention.
At the time of publication, all information and illustrations refer to the product at the
time of publishing. Because Yamaha Motor Co., Ltd. constantly refines and improves
its products, no retroactive obligation is incurred.
This Yamaha Operator’s Manual should be considered a permanent part of the snowmobile and must remain with the snowmobile at time of resale. If the snowmobile
changes ownership, contact your Yamaha dealer.
Every Yamaha snowmobile meets or exceeds the standards of the Snowmobile Safety
and Certification Committee and displays the SSCC decal. Yamaha endorses and
encourages the safe use of all snowmobiles. Always wear a helmet and eye protection. Drive with caution, observe all state and local laws, and respect the rights of others. International Snowmobile Manufacturers Association (ISMA) members like
Yamaha do their part to improve trails, sponsor events, and generally support the
sport of snowmobiling. As a member of the National Snowmobile Foundation,
Yamaha promotes snowmobiling through education, charity, and research programs.

The figures quoted are emission levels
and are not necessarily safe working levels. Whilst there is a correlation between
the emission and exposure levels, this
cannot be used reliably to determine
whether or not further pre-cautions are
required. Factors that influence the actual
level of exposure of work-force include
the characteristics of the work room, the
other sources of noise, etc. i.e. the number of machines and other adjacent processes, and the length of time for which
an operator is exposed to the noise. Also
the permissible exposure level can vary
from country. This information, however,
will enable the user of the machine to
make a better evaluation of the hazard
and risk.

Getting Ready to Operate the SRX120 Safely
E.
TETHER SWITCH — The
WARNING
This vehicle is designed for daylight
use by children of no less than 6
years of age while under mandatory
adult supervision. Use of this vehicle
on public roads is not allowed.
NOTE: This section and Operat-
ing the SRX120 section must be
read and explained to the child/
operator by the owner/parent/
guardian. Refer to Control Locations or the snowmobile while
explaining this section.
Like most boys and girls, you are anxiously waiting to drive the snowmobile.
Remember that the snowmobile is not a
toy. It must be driven carefully at all
times!
First, you must understand the controls,
know where the controls are, and know
how to use them correctly.
BRAKE LEVER — To slow
A.
down or stop the snowmobile, the
brake lever should be pulled
(squeezed) toward the handlebar
grip.
NOTE: When the brake is being
used, the throttle lever must be in
the idle (released) position.
B. THROTTLE LEVER — Controls
the speed of the snowmobile. The
closer the throttle control lever is to
the handlebar grip (the more it is
squeezed), the faster the snowmobile will go.
IGNITION SWITCH — When
C.
the key is in the OFF position, the
engine will neither start nor run. If
the key is in the RUN position, the
engine will start and run.
EMERGENCY STOP SWITCH
D.
— If something happens that you do
not understand or if there is an emergency, move the emergency stop
switch to the OFF (down) position to
immediately stop the engine.
engine will neither start nor run
unless the tether switch cap is connected to the tether switch located
on the top right-hand side of the console. The tether cord
clipped to the operator’s right wrist
before attempting to start the engine.
Second, you must check several things
every time before the engine is started.
A. Make sure the brake lever works
properly (moves freely) by pulling
(squeezing) the brake lever and
releasing it several times.
B. Make sure the throttle lever works
properly (moves freely) and that it
snaps back to the idle position
quickly when it is released. The idle
position is when the throttle lever is
farthest away from the handlebar
grip. If the throttle lever does not
snap back quickly, the engine must
not be started and the throttle system
must be repaired.
C. Make sure that you have enough
clothes on to keep yourself warm but
NEVER wear clothes such as long
or loose scarves or long shoe laces
that could get caught in a moving
part of the snowmobile.
D. Make sure that the engine hood and
all access panels are closed, and that
the windscreen and all protective
guards are securely in place.
Third, make sure that you can answer yes
to all of the following questions before
each ride.
A. Do you have permission from the
owner or parent or guardian to operate the snowmobile?
B. Do you have an approved safety hel-
met on?
C. Are you wearing something to pro-
tect your eyes (such as goggles or a
visor)?
D. Are you dressed warmly enough?
E. Has your parent or guardian checked
to make sure you have enough gasoline?
MUST BE
4
F. Do the throttle lever and brake lever
move freely?
G. Are all shields and covers in the
right place and is the hood securely
latched?
H. Do you have a safe area to ride in? Is
the area free of rocks, wires, trees,
traffic, etc.?

Operating the SRX120
WARNING
Operation is allowed only within the
ambient temperature range of 5 °C to
minus 20 °C.
You must be a responsible, careful, and
considerate snowmobile operator at all
times. Your safety is our concern and
must always be yours.
A. When you are learning how to oper-
ate the snowmobile, have a parent or
guardian take you to an open area to
practice figure eights, starting, and
stopping. This practice is important
and will give you a good “feel” of
the snowmobile. You will also be
able to learn how the snowmobile
handles under different conditions
(deep snow, hard-packed snow, etc.).
B. Always sit on the seat and keep both
feet on the running boards when
operating the snowmobile. Do not
get off the snowmobile until it has
come to a complete stop.
C. Never drive the snowmobile faster
than a safe speed. Do not drive too
close to roads, buildings, trees, other
snowmobiles, or people. Never
show off!
D. Never operate the snowmobile
unless the headlight and taillight are
in working order.
E. This snowmobile is designed for lei-
sure use by a single occupant. Do
not carry any passengers.
F. Do not pull sleds, sleighs, etc.,
behind the snowmobile.
G. If you get stuck, shut the engine off
and get help.
